Description

The blanking funnel of belt transporter

One, technical field: the utility model belongs to industrial and mining enterprises' inside transport apparatus field.

Two, background technology: as the ore in the smelter, sintering deposit, limestone, coal and coke etc., all need transhipment in process of production, the equipment of transhipment is exactly belt transporter, and belt transporter often is not one, but many.Be transported on another belt transporter from a belt transporter, a drop is arranged between two belt transporters, the height of this drop can reach between 3 meters to 5 meters.These material will produce collision in the process that falls, produce dust, add in the process of blanking to produce air-flow, and dust just flies upward everywhere, has produced pollution.Handle now the way of the pollution of this dust, adopt a material blanking tube between two belt transporters, this material blanking tube has solved subproblem, but still is that dust flies upward in the lower end of material blanking tube.Therefore, also to further improve the way of existing material blanking tube form dedusting.

Three, summary of the invention:

The purpose of this utility model designs a kind of drop height that can reduce material exactly, reduces the blanking funnel of belt transporter of the impact of collision and air-flow.

The technical scheme that the utility model technical solution problem is adopted is: on the both sides of material blanking tube, two minor axises are fixed in welding symmetrically, the chevron pointing pipe link that can swing is housed on the minor axis, the discharging opening place of an arc flashboard in material blanking tube fixed in welding on the pipe link, fix an axle on the limit of arc flashboard, on the axle connecting rod is housed, the other end of connecting rod has pin to be connected with cylinder piston rod, on the blanking tube wall, do the cavity of a protrusion, be screwed a time-delay switch on the cavity wall, on the blanking tube wall at cavity place, adorn a spring leaf with bearing pin.

The utility model beneficial effect is: owing to reduced blanking height and gas shock, can reduce the generation of dust, reduce the pollution of dust, improve environmental health.

Four, description of drawings: Fig. 1 is the cross-sectional schematic of facing of the present utility model, and Fig. 2 is the cross-sectional schematic of facing of second embodiment, and Fig. 3 is the A portion cutaway view Amplified image of Fig. 1, Fig. 2, and Fig. 4 is the B-B cross sectional drawing of Fig. 2.

Five, the specific embodiment: describe details of the present utility model and service condition in detail in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4.The alternate position spike that the utility model mainly reduces blanking reduces the collision of material, produces dust less, reduces the speed of air-flow simultaneously, reduces dust and flies upward, and improved environmental health.Material is shipped by belt transporter (1), falls belt transporter (20) by material blanking tube (2) and transports.Both sides in material blanking tube (2), two minor axises (26) are fixed in welding symmetrically, the chevron pointing pipe link (27) that can swing is housed on the minor axis, welding is fixed an arc flashboard (9) and is located in the discharging opening (7) of material blanking tube (2) on the pipe link, fix an axle (10) on the limit of arc flashboard (9), on the axle connecting rod (11) is housed, the other end of connecting rod has pin (12) to be connected with cylinder (14) piston rod (13), on material blanking tube (2) wall, do the cavity (6) of a protrusion, be screwed a time-delay switch (5) on the cavity wall, on material blanking tube (2) wall that cavity (6) is located, adorn a spring leaf (4) with bearing pin (3).Have lead (28) to be connected between time-delay switch (5) and the electromagnetic valve (16), the valve rod of electromagnetic valve is connected with cylinder valve (15).Working process of the present utility model is: when belt transportation (1) ships material and falls material blanking tube (2) lining, arc flashboard (9) is the discharging opening (7) of closing material blanking tube, when material is filled spring leaf (4) position, material is with regard to pressing spring sheet (4), switch when spring leaf just rolls (5), energized, power supply joins by lead (28) and electromagnetic valve, electromagnetic valve (16) is work just, and the valve rod of electromagnetic valve promotes the valve rod work of cylinder valve (15), just can make piston rod (13) work of cylinder (14), because piston rod work, arc flashboard (9) just can be drawn back and be closed, when drawing back with regard to blanking, blanking not just when closing.Cylinder valve (15) has admission pipe (17) and eduction pipe (18) to communicate with cylinder (14).In order to make the material in the material blanking tube (2) reach balance, separated in connecting rod (11), screw thread in the processing of the two ends of gap is adorned a threaded adjust bar in two (21) on the internal sealing plug.Because adjust bar (21) has been arranged, the opening of arc flashboard has just had control, has also just controlled material conveying amount, and material is kept certain height in material blanking tube.Cylinder (14) is contained on the flat board (24).Second example: the both sides fixed support of locating at the discharging opening (7) of material blanking tube (2) (25), fixing guide groove (22) on the support is equipped with plate (23) in the guide groove, be fixed with axle (10) on the plate limit, and axle is connected with connecting rod (11).Because plate (23) moves in guide groove (22), this has just controlled transportation volume, also just controls the height of material, makes material keep the height of wanting in advance in material blanking tube.
